As described above, the conventional LED shoe has a very low degree of freedom of expression, which is insufficient for use as a fashion item, and can not detect the user's walking habits and the like.

Therefore, the present invention proposes a smart LED shoe that solves the problems of conventional shoes.

First, the structure of a general shoe is explained.

2 is a perspective view showing the structure of a general shoe.

As shown in FIG. 2, the shoe generally includes an insole 10, an insole 20, a midsole 20, a midsole 20, and an outsole 30, which are in contact with the ground, ). However, children's shoes may not include midsole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. In addition, the embodiment described below does not unduly limit the contents of the present invention described in the claims, and the entire configuration described in this embodiment is not necessarily essential as the solution means of the present invention.

3 is a cross-sectional view illustrating the structure of a smart LED shoe according to an embodiment of the present invention.

Referring to FIG. 3, the smart LED shoe may include a tactile sensor 100, a plurality of LEDs 200, a controller 300, a power supply 400, and a wireless communication unit 500. However, the components shown in FIG. 3 are not essential, and a smart LED shoe having more or fewer components may be implemented.

First, the tactile sensor 100 is disposed on the lower side of the solenoid, and senses the pressure applied by the foot of the shoe user, thereby generating the pressure signal and the output signal of the pressure applied position.

The tactile sensor 100 may use one of a contact resistance type, a capacitive type, and a piezoelectric material type. A portion where the tactile sensor 100 senses the pressure may be disposed at a predetermined position on the underbody.

For example, two forefoots corresponding to the anterior position of the foot, and one for the hindfoot corresponding to the posterior position of the foot may be disposed. However, the portion where the tactile sensor 100 senses the pressure is not limited thereto.

In addition, the tactile sensor 100 may be integrally attached to the insole, but may be removable from the insole for cleaning the insole.

In order to manufacture such a tactile sensor 100, a sensor part of the tactile sensor 100 may be inserted into a metal mold, filled with a liquid polymer or the like, and cured.

However, the sensor part of the tactile sensor is a very sensitive sensor, and if manufactured by the above method, there is a great risk that the sensor will fail. Therefore, the tactile sensor 100 can be manufactured by including a plurality of tactile sensor modules as follows.

FIG. 4A is a cross-sectional view of a tactile sensor module 110 according to one embodiment of the present invention, and FIG. 4B is an exploded cross-sectional view of a tactile sensor module according to an embodiment of the present invention.

4A and 4B, the tactile sensor module 110 may include a sensor upper layer 111, a sensor portion 112, a sensor intermediate layer 113, and a sensor lower layer 114.

First, the sensor upper layer 111 directly contacts the lower surface of the insole, and the pressure applied by the user's foot is transmitted through the insole. In addition, a recess 111a may be formed on the lower surface of the sensor upper layer 111, and a plurality of recesses 111a may be formed at predetermined intervals as shown in FIGS. 4A and 4B.

The sensor unit 112 is a key component of the tactile sensor module 110. The sensor unit 112 senses the pressure and generates an output signal with respect to the intensity and position of the pressure. And can be inserted into the formed concave portion 111a. A plurality of sensor units 112 may also be provided.

Next, the sensor middle layer 113 is positioned on the bottom surface of the sensor unit 112 inserted in the recess 111a to seal the recess 111a.

If the sensor unit 112 is exposed to water or an adhesive is applied to the tactile sensor module 110 when manufacturing the tactile sensor module 110, there is a high probability that an error occurs in the pressure measurement. In order to prevent the occurrence of such an error, the sensor unit 112 is inserted into the concave portion and then the concave portion is sealed using the sensor intermediate layer 113. However, the tactile sensor module does not include the sensor intermediate layer 113, and may be composed only of the sensor upper layer 111, the sensor portion 112, and the sensor lower layer 114.

Particularly, in the case of the tactile sensor module having an array structure, since there are many sensor portions 112, if the sensor middle layer 113 is used, the defective rate can be remarkably lowered when the tactile sensor is manufactured.

Next, the sensor lower layer 114 is attached to the lower surface of the sensor upper layer 111 and the lower surface of the sensor middle layer 113 to close the tactile sensor module 110. The sensor portion 112 is secure because the recess 111a is sealed by the sensor intermediate layer 113 even when a liquid adhesive such as a bond is used to attach the sensor lower layer 114. [

The load supporting portion 114a may be formed under the sensor lower portion 114. The load supporting portion 114a may be formed below the sensor portion 112. When the pressure is applied, (112).

Meanwhile, in order to connect the plurality of tactile sensor modules to the control unit, complicated wiring is performed in order to transmit the signals output from the respective modules to the control unit. When using an N * N array tactile sensor module, at least 2N output signal transmission lines are required. When there are several tactile sensor modules, there is a problem that a large number of output signal transmission lines are provided, which is very complicated.

To solve this problem, the following tactile sensor 100 can be used.

5A shows a cross-sectional view of a tactile sensor according to one embodiment of the present invention.

Referring to FIG. 5A, the tactile sensor 120 may include a plurality of variable resistors 121, a first line 122, and a second line 123.

The plurality of variable resistors are disposed at predetermined positions on the underbody to sense the pressure, and the resistance value changes depending on the intensity of the pressure applied to the disposed position.

The first line 122 is in contact with the top of each of the plurality of variable resistors 121, and connects the plurality of variable resistors 121 in parallel.

The second line 123 is connected to a lower portion of each of the plurality of variable resistors 121. The plurality of variable resistors 121 are connected in parallel to each other, And a resistor 123a, one end of which is grounded (GND).

The tactile sensor applies a first input voltage to the other end B of the second line 123 and outputs the first input voltage to the other end A of the first line 122 to generate an output signal for the pressure applied position The second input voltage is applied to the other end A of the first line 122 and the second input voltage is applied to the second line 123 to generate an output signal with respect to the intensity of the applied pressure, And the value of the second output voltage outputted to the other end B can be used.

5B shows a circuit diagram of a tactile sensor according to an embodiment of the present invention.

5B, when the pressure is applied as shown in FIG. 5B, the tactile sensor of FIG. 5A may be connected to the other end B of the second line 123 to generate an output signal for a position where the pressure is applied. And a first output voltage value output to the other end A of the first line 122 is used. The first output voltage value can be obtained by using the following equation (1).

A second input voltage of the other end (A) of the first line 122 is applied to generate an output signal with respect to the intensity of the applied pressure, and a second output voltage of the second output voltage Value can be used. The value of the second output voltage can be obtained by using the following equation (2).

The tactile sensor 120 may include a plurality of tactile sensors connected in series as shown in FIG. 5C, and a lower metal layer between the plurality of tactile sensors may further include a resistor.

5C is a cross-sectional view of a tactile sensor of the contact resistance type according to one embodiment of the present invention.

5C, the coating layer 132a and the metal layer 133a are formed in order on the polymer film 131a having a predetermined thickness and the resistor 134a is formed on the metal layer 133a And a lower plate manufactured by sequentially forming a coating layer 132b and a metal layer 133b on the manufactured upper plate and the polymer film 131b having a predetermined thickness and forming a resistor body 134b on the metal layer 133b. And a spacer 135 so as to face the resistor 134a of the upper plate and the resistor 134b of the lower plate.

Figure 5d shows an insole in which a tactile sensor according to one embodiment of the present invention is disposed.

Referring to FIG. 5D, it is possible to sense the pressure in three portions of the lower portion of the insole and receive the output signal of the tactile sensor using only the first line and the second line.

That is, when the tactile sensor as shown in FIGS. 5A to 5D is used, it is possible to perform wiring with a simple structure, and the calculation is very simple even when the control unit 300 processes the output signal.

Next, the plurality of LEDs emits light according to the intensity, color, and light emission pattern determined by the controller 300. [ 6A shows a plurality of LEDs attached to a midsole according to one embodiment of the present invention, and FIG. 6B shows a plurality of LEDs attached to an outsole according to one embodiment of the present invention, FIGS. 6A and 6B The plurality of LEDs 200 may be attached to the sides of the midsole or outsole of the shoe. Although not shown, the plurality of LEDs may be attached to any position where light emitted by a plurality of LEDs can be recognized from the outside of the shoe, such as a shoe upper or a brand logo of a shoe, as well as a side periphery of a midsole or an outsole .

In addition, the plurality of LEDs may form an LED strip 210 in which a plurality of LEDs are connected by a single line, and an LED reflector 220 (Reflector) is further provided to extend an irradiation area of light emitted by the plurality of LEDs .

As a method of placing a plurality of LEDs on a shoe, there is a method in which a plurality of LEDs are put in a mold and a liquid polymer is filled to make a midsole or an outsole itself.

7 illustrates a midsole / outsole including a plurality of LEDs according to an exemplary embodiment of the present invention. The midsole / outsole 231, the midsole / outsole bottom layer 233, the plurality of LED layers 232 And a plurality of LED layers 232 are inserted between the midsole / outsole upper layer 231 and the midsole / outsole lower layer 233 and adhered using an adhesive.

Next, the control unit 300 controls the overall operation of the smart LED shoe, and may be mounted on the middle portion of the midsole in the smart LED shoe, but the mounting position is not limited thereto.

The controller 300 determines at least one of the color, intensity, and light emission pattern of the light emitted by the plurality of LEDs using the output signal of the intensity and the position of the pressure generated by the plurality of tactile sensors 100. In addition, it is possible to determine that only a part of the plurality of LEDs emits light using the output signal.

At this time, the controller 300 may determine at least one of light color, intensity, and light emission pattern according to a predetermined light emission mode. That is, even if the user applies a pressure to the heel, the intensity of the LED light emitting in accordance with the light emitting mode is determined instead of the LED of the heel unconditionally.

As an example of such a light emitting mode, a light emitting LED is determined according to the position of the pressure applied to the tactile sensor 100, and the intensity of the light emitted by the LED is determined in proportion to the intensity of the pressure sensed by the tactile sensor 100 . However, the light emitting mode is not limited to this example.

Meanwhile, when at least one of the pressure intensity sensed by the tactile sensor 100, the pressure applied position, and the pressure applied time corresponds to a preset pattern, the controller 300 may set the predetermined light emitting mode to another light emitting mode And the color, intensity, and light emission pattern of the light emitted by the plurality of LEDs can be determined according to the changed light emission mode.

In order to change the light emitting mode of the conventional LED shoe, the user has to operate the switch of the LED shoe, so that it is very troublesome to change the light emitting mode. However, according to the present invention, there is an advantage that the light emitting mode can be freely changed even while walking.

An example of a pattern for changing the light emission mode will be described with reference to the drawings.

FIG. 8A shows a first pattern for changing the light emitting mode according to one embodiment of the present invention, and FIG. 8B shows a second pattern for changing the light emitting mode according to an embodiment of the present invention.

Referring to FIG. 8A, the first pattern is a pressure applied to the hindfoot twice in succession. When the tactile sensor 100 senses the same pressure as the first pattern, the controller 300 can change the light emitting mode.

Referring to FIG. 8B, the second pattern is such that the pressure is applied to the tactile sensor 100 in a clockwise or counterclockwise direction.

That is, when pressure is applied to the second part 150 of the tactile sensor and pressure is applied to the third part 160 of the tactile sensor after the pressure is applied to the first part 140 of the tactile sensor, Direction.
